The occurrence of Ethyl 5-(tert-butylthio)-2,2-dimethyl-4-oxopentanoate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Ethyl 5-(tert-butylthio)-2,2-dimethyl-4-oxopentanoate (CAS 136558-13-9), molecular formula C13H24O3S and molecular weight 260.39 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, Ethyl 5-(tert-butylthio)-2,2-dimethyl-4-oxopentanoate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 260.39 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
